Hello,
I have a custom usercontrol, of which I have two instances of in my aspx
page. Both the usercontrol and page have codebehind. In the page
codebehind, I want a member variable for each usercontrol. My problem is
that I keep getting a compiler error on the usercontrol variables in my
page codebehind (BC30002: Type 'CityGeoPosSelectClass' is not defined.)
For whatever reason, my usercontrol class is not being declared in the
page codebehind file. I've read every article I could find on this and I
still can't seem to get this to work. I would greatly appreciate if
someone would take a look at this and give me some pointers on what I'm
doing wrong here (relevant code below).
I'm not using Visual Studio .NET to develop this, and my version of the
..NET framework is 1.1.4322.573 with IIS 5.1. Thanks for your time and
attention.
Regards,
N. Demos
